To all whom t may concern.'

v Be it known that I, PETER SGHIEFIER, en-

' gineer, a subject ofthe King of Prussia, re

siding at N o. l .Stephanstrasse, Aachen, in`

the Kingdom of Prussia, Empire ofv Germany, have invented certain newand useful Improvements in Pile-Planking of Rolled Iron; and I'do hereby.declare the following- -A to be a full, clear,

and exact description of the invention, such as V.Will enable-othersskilled in the art to which it appertains to -planking in dilierentrepresentation-forms.

' According to Fig. l the pile-planking con- I sists of approximateS-shaped sections equal vto one another which form mg of a trough-shapedcross-section, while in Fig.

In accordance with Fig; 3 a scalar-'iform pile-planking is formed ofZ-shaped sections which are exactly like one another,- while in Fig. 4two Z- places, 1s

shaped sections having differently formed ends, fserve for theproducing'or manutanturing of the same planking.

In all representations the connecting places of the pile-planking aresituated within its symmetrical axis, whereby the work of ramming isfacilitated. In spite of this, the weake. g of the wall caused by theguiding only slight, as between two interrupted slanting walls, a fullslanting wall is planking according to Figs. 3-4

always arranged. Especially, the pile'- advantage that the pointed edgesof the i I planks exert a. wedge-like effect against outer 'edge oftheplank, the .same is directly dipressure. If therefore any concussion orforce Works or operates on the pointed onter vided into the twodirections of the slanting walls and is then transferred to the abut-Amentof the back wall.

Each of the planks comprises approximately Z-shaped body portion 5comprising a long member 10 having angular extensions Specificationof'Letters Patent.'

Application filed September 24, 1912. 'Serial No. 722,115.

'11 thereon. vCarried, by these extensions of the body portion are thevmeans for interlocking the planks to form a structure. Upon one end ofthe'plank is formed a peculiarlyshaped head outwardly aring shoulder' 7.This head 6,

is adapted to be inserted into a socket 8, carried by another one of theplanking units.

VThis socket is formed to make a sliding fit for; the head 6, and isprovided with an inwardly turned member 9, which engages the shoulder 7,on the head 6. 'These interlocking ortions of the planking units areplaced 6, provided with an 'y at t e abutting ends of the plankingunits.

The units may be provided with two. sockets,

with two heads or a head and a socket asdesired. These units are slidone vinto .the

other, the socket of one member receiving' Vthe head of the othermember. Thus unfavorablev working strains or spans in theplank-cross-section areavoided. v

` Having thus described my invention, what I claim is plurality ofdetachable planking units',- each of the units consisting of a bar bentto form 'a relatively long portion',

a plurality ofrelatively shorter extensions oppositely disposed one ateach edge, or they maybe provided- 1. A metallic nsheet lpilingcomprising a with relation to said longer portion andV at anglesthereto, interlocking fastening means carried by said shorter portions,said inter locking means comprising sockets formed with shouldersand-heads adapted to be inserted in the sockets. l

2. In a metallic sheet piling, the combination -with a plurality ofseparable units, of fastening meanscarried by saidunits, said `fasteningmeans lying in the same plane, a plurality of relatively short angularlydis'- posed extensions adjacent each of said fastening means, arelatively longer'member connecting said shorter extension said memberbeing oppositely and angularly disposed relative thereto.

In testimony whereof I have signed my name to this specification in thepresence vof two subscribing witnesses.
